In this dissertation, the different perspective and alternative approaches of the cost allocation are proposed. The focuses of this dissertation are discussed in the power transfer, transmission utilization, and frequency regulation.
In the power transfer, the straightforward method using Y-bus matrix is proposed, in which the injection current between generation and load is considered while the current through the complicated network topology is not traced. The interaction of real and reactive power for each generator-load pair can be clearly identified. Besides, the proposed strategy for determining the transmission utilization is based on a new perspective on the dissipated heat caused by the line resistance rather than the traditional power flow method.
In the developing the cost allocation of Primary Frequency Regulation (PFR), this dissertation proposes a series of methods for analyzing load variations and utilizes the actually recorded data as an analytic case. It expects to obtain the characteristics of load variations during different time periods, which is taken as basis to establish the cost allocation index of PFR. On the other hand, the transient response of the individual generating units to PFR service is analyzed in this dissertation. The quantitative PFR performance index of individual generating units are established according to their dynamic properties and operation models. Furthermore, load following is another important subject concerning with the frequency regulation. How to schedule the energy and frequency regulation in a security-constrained electricity market is also addressed.
